Specification of Letters Patent.

Application filed August 17, 1818. Serial No. 250,319.

vente'd certain new and useful Improvements in Feeding Attachments for Crown- Cork-Making Machines, of which the followingjs a specification.

he present invention relates to machines for manufacturing bottle-, can-, and like closures of the cap variety, including those termed crown corks. The invention pertains more particulary to means for feeding the sealing disks of cork or similar material 7 of the closures to the assembling devices of the machine.

In one type of these feeding attachments, a hopper is used into which the sealing disks are placed indiscriminately, in combination with'means which feed the disks into a vibrating tube that stacks the same. With these tubes difliculties have been experienced in that the sealing disks are' apt to travel therein edgewise, which necessitates almost continuous supervision by the attendant, in order to insure an uninterrupted operation of the device.

The main object of the present invention is to so construct the stacking tube that the disks therein are arranged continuously and automatically one on top of another, or in other words in proper position to be removed by the transporting means of the as-' sembling devices.

With these and other objects in view, which will more fully appear as the nature of the invention is better' understood, the same consists in the combination, arrangement and'construction of parts hereinafter described, ointed out in. the appended claims and illustrated in the accompanying drawing, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawing, which represents a central vertical section taken through a feeding attachment constructed in accordance with the present invention.

In the drawing, the numeral 10 indicates a portion of the frame of a crown cork assembling machine, having upon its table P01110111]. mounted an upwardly extending support 12, which carries a hopper 13. This hopper may be of any suitable construction, for lnstance in the case illustrated in the drawings, 1t comprises a cast iron member 14, held upon the support 12, and to the said member is attached a hopper body 15, preferably made of sheet iron. The outlet of the hopper is denoted by the numeral 16, and is constituted by part of the member 14 and by an inclined substantially diamet-- rically extending plate 17, the latter being attached in any suitable mannerto the said member and projecting below the lower edge thereof, for a purpose hereinafter to be described. The hopper discharges into a shallow receptacle 18, that is disposed below the same and is provided with a slanting bottom 19, having a circular discharge opening 20, the diameter of which is slightly larger than that of an individual sealing disk. The discharge opening is formed, preferably, in the lowermost portion of the slanting bottom of the receptacle 18- and is out of alinement with the outlet of the hopper, the latter discharging onto a higher portion of the slantin bottom. of the said receptacle. The incline plate 17 projects into the receptacle 18, but stops short a suitable distance above the bottom of the latter, thereby permitting the sealing 'disks to pass toward the discharge opening 20, preventing, however, too many of the same to pass at a time toward the said opening. The plate 17 thus divides the receptacle 18 into a disk receiving portion and a discharging portion.

The receptacle 18 is oscillated or reciprocated in relation to the hopper. For this purpose there may be provided any suitable means, for instance there may be formed .21 and the guides 22 extend horizontally, so

that the receptacle 18 will be reciprocated in tuted by a short tubular extension 29, that projects below the bottom thereof and fits somewhat loosely into a tube 30. The lower end of this tube is attached to the upper end of a resilient support 31, the lower end 32 of which is fixed to a bracket 33, the latter being secured to the support 12, above described. The outlet of the tube 18 m alinement with the mouth 34 of a statlonary, preferably, vertically extending tube 35, leading to the transporting means 36 otthe machine, which conveys the seallng disks one after the other to the assembling mechanism. The tube 35 is held above the transporting mechanism by the bracket 33. The tube 30 is-provided with lengitudmalslots 37, permitting of an insertion of a pointed instrument for the purpose of properly arranging the disks therein, should, by acoldent, some of the disks travel therein edgewise.

The inner face of the tube 30 is constituted by a plurality of superimposed inverted frusta 38 of a cone, or in other words, the inner face of the tube 30 has annular downwardly sloping projections. This arrangement aids in stacking the disks, that is, if any one travels in the said tube in inclined posi-.

tion, it will be caused, as the said tube vibrates, to assume a horizontal position. This is mainly due to the fact that the inclined disks are retarded by the sloping projections. The smallest diameter of the tube 30 is larger than the diameter of the disks to be stacked, thereby permitting the disks to be brought in said tube into horizontal position.

The operation of this device is as follows: A mass of sealing disks is placed indiscriminately into the hopper, part of the same sliding through the outlet 16 into the receptacle 18. When now this receptacle is reciprocated, the tube 30 is caused to move therewith and to swim around the point 32 of the resilient mem er 31. The disks in the said receptacle are thus caused to pass'toward the discharge opening 20 therein, finding their way into the tube 30, the continuous vibration of which causes a proper stacking of the disks therein. No matter in what position they arrive in the said tube,

they will be brought, by the continuous vibrating motion, before they reach the mouth of the tube 35, into substantially horizontal positions and into exactly horizontal positions as they pass into the stationary tube 35. The thickness and more or less curved shapes of the disks do in no way afiect the proper operation of the device. 1 f

The inclined plate 17 prevents a clogging of the discharge opening of the receptacle 18, in that it permits, at a time, only a 11mited number of disks to move toward the said opening. The said plate, in woperation with the reciprocating receptaole l8,

serves alsoto'agitate the mass of disks, and

lar device has been described for feeding the sealing disks into the vibrating stack-' ing tube, any other means may be employed without departing from the invention, which liesmainly in the provision of a vibrating stacking tube, the inner face of which is provided with purpose set forth.

What I claim is:- I p 1. In a device for stacking disks, the combination with a receptacle having a discharge opening, of a downwardly extending tube connected with said receptacle. and into which the latter is adapted to discharge through said opening, the inner 'face of said projections, for the tube being constituted by a plurality of super-imposed inverted frusta of a cone, and means for shaking said receptacle and tube.

2. A device for stacking disks, including a tube having an inner face constituted by a plurality of superimposed inverted trusta of a cone, and means for shaking the said tube.

3. In a device for stacking disks, the combination with a receptacle having a discharge opening, of a downwardly extending cylindrical tube connected with said receptacle and into which the latter is adapted to discharge through said opening, the inner face of said tube being provided with annular downwardly sloping projections, and means for shaking said receptacle and tube.

4:. A device for stacking disks, including a cylindrical tube having its inner face provided with annular downwardly sloping projections, said projections being fixed to said tube and the smallest diameter of said tube being larger than the diameter of the disks to be stacked, and means for shaking said tube.

5.
